Transcription

1 Regional Human Anatomy (HBA 461/561/540): Course Objectives This is a 5-credit course that consists of 1-hour lectures followed by 3-hour labs. It is organized into three modules (see syllabus): Module I: Module II: Module III: Thorax and abdomen 12 lectures, 36 hours of lab Head and neck 11 lectures, 33 hours of lab Limbs 10 lectures, 30 hours of lab General Organization In lecture, major anatomical topics are covered, but students are additionally responsible for readings in the textbook (Core Concepts in Anatomy) as well as for material provided to them in handouts or as files posted on the class web page. PDFs of all PowerPoint presentations are made available to the students prior to lectures on the class web page. For the laboratories, the students are organized in groups of five or six and perform whole-body dissections following instructions found in Grant s Anatomy Lab, a customized online dissector. During dissections, students are assisted by faculty, graduate, and medical student teaching assistants. X-rays, CT scans, and MRI images are made available in lab as well as on the class web page, and identification of major structures is required. A list of essential structures is posted for each module for self-study. The teaching staff assists in case of questions. During dissection of the thorax and abdomen, students are asked to identify abnormalities and pathologies in the body that they dissect. Students are responsible for all dissected structures, not only from their own dissections, but also in cadavers dissected by others, the listed structures on X-rays and scans, and all bones of the human skeleton and their major topography. Groups of two to three students each share a bone box with the bones of one half of a human skeleton. These boxes are signed out by students at the beginning of the course, and they are allowed to take them home for the duration of the course. Each module has a short quiz roughly at the mid-point and a major examination at the end. Quizzes consist of a written part (with ~15 multiple choice questions), and a laboratory part (with ~ 25 IDs) in which structures that are marked on cadavers, X-rays, and bones must be identified. Quizzes do not count toward students' grades. Exams count for 100 points each (50 points for the written portion and 50 points for the lab portion). The format for exams is like that for quizzes. Final course grades are based on cumulative percentages from the three exams. Quiz and exam answer keys are posted immediately after the tests. Students are allowed to take the written exam questions with them. A photocopy of the Scantron sheet with their answers for the written part and their lab exam is handed back to them immediately after grading (usually the next day). Students are encouraged to follow up on errors. Course information is available on a course web site at the following address: 1

2 This web site lists the faculty and student assistants teaching in the class, their office locations, and office hours. Students also have access to the course objectives on this site, exams from previous years (complete with keys), a photographic atlas of the anatomy of the central nervous system (developed specifically for this class), a collection of radiological images (developed specifically for this class), copies of all handouts, and links to selected anatomy web pages. Also posted on the web site is the syllabus, schedules of special review sessions, and quiz and exam keys and scores (anonymously) as soon as available. The grading policy for the class is as follows: HBA 561/540: A = 90%, B = 80%, C= 70 %, D = 60% HBA 461: A = 85%, B = 75%, C = 65%, D = 55% If a curve is applied, it is to the students advantage; i.e., standards for grades are never raised, but they may be lowered.
